Can't see any entries in Linux Firewall


I have a clean, default Webmin installation but I cannot see any entries in the Linux Firewall (see attached).

Any help appreciated.

Go to Webmin - Network - Linux Firewall - Reset Firewall - Block all except ports used for virtual hosting, on interface ## - Setup Firewall - Apply Configuration.

The result is not perfect but its a good start. How to tweak your firewall after that best would be to check google, you will find tons of articles.
